i was trying to find the limits of a function when i came onto a problem
square root of ( (x^2) + 9x + 3)
multiply by (1/x)
this should simplify to:
square root of ((x) + (9/x) + (3 / (x^2) )
how does this work?
i was trying to slove this problem
find the limit of
((square root of ((x^2) + 9x + 3)) minus x
lim when x approaches infinity
just convert the 1/x into square root of (1/ (x^2)
this makes it possible to simplify the stuff under the main square root.
this is why x^2 simplifies to 1, 9x simplifies to 9/x, etc.
thanks to me?
